I don't think we should be explaining how to make a Free Body Diagram. Similarly, I'm not going to explain the "method of sections" to...

that's a crap load of precision ! maybe 0.47 +/-0.01 ? ... or 15/32" +/- 1/64"

"creating artificial geodesic by asymmetrically spinning an extended object" ... how do you do this without adding energy ? You're...

"procrastinating and just not caring" ... yeah, that'll do it ! "planning to study hard in grade 12 to at least get 85-95 in all the...

I have just about no idea what you are doing !!?? what you found may be locations, but look to me to be deflections. let's start at...

by looking at the model ! maybe you can see an echo of the model input in the output, and search for the node. Or maybe ask ANSYS...

do you import your American Autocad model and change the units ? I've never experienced "American drawings love rounding up dimensions"...

I don't know what you mean. I see this as a crane arm (AD) with a control arm (BC) and the two are pinned together at B. There cannot...

"One bar represents temporal velocity and the other spatial velocity. As one increases the other decreases so that the sum is always 0."...

and those loads are "F" ... ? CB is a "two force member". Don't get the question, what else do you think is happening ? If I haven't...

"We've begun with the mechanical version" ... ? do you mean someone has built this already ? I thought it was "just" a thought...

sorry, but what ? are you interpreting B as a fixed point ? I think everyone else thinks CB is pinned onto AD; how could it be...

when you say "resilience", you mean "fragility" ?

I think Dave has solved it (I was wrong about the direction of F, it is to the left). Force F is found simply by moments about A ...

I wonder if this idea violates the laws of thermodynamics, and could be a "perpetual motion" machine ? It sounds like you are trading...
